When I first bought my car, it came with a one-touch start feature, typically paired with two smart keys. One key stays in my pocket, allowing me to start the engine effortlessly—super convenient. The other serves as a backup, kept safely hidden just in case. I remember one time the key battery died, but a quick replacement of the coin cell got it working again. It's best to check the key battery regularly to avoid any issues when you're out and about. If a key is lost, you’ll need to visit a 4S store to get a replacement, which can cost a few hundred bucks—pretty pricey—so protecting the backup is crucial. Some new car options might only include one key, so it’s safer to confirm the specifics with the model before buying.
